Method and system for having intelligent control over granary ventilation system

Abstract

The embodiment of the invention provides a method and system for having intelligent control over a granary ventilation system. The method comprises the steps that sensor detection modules acquire temperature and humidity data inside and outside ventilation windows, ventilation control modules send the temperature and humidity data inside and outside the ventilation windows to a mobile terminal through a wireless communication network, a master control server judges whether one ventilation window needs to be opened to carry out ventilation operation or not according to the average temperature and the average humidity, which are calculated by the mobile terminal, inside and outside the ventilation window on the basis of a set ventilation control strategy, and if yes, a ventilation instruction is sent to the ventilation control module corresponding to the ventilation window. According to the method and system for having intelligent control over the granary ventilation system, the information of the temperature and humidity inside and outside a granary and the status information of ventilation portions can be acquired in real time, and the ventilation portions can be automatically opened and closed in a wireless communication mode through the master control server and the mobile terminal so that automatic ventilation operation can be carried out.

Description

technical field

[0001] The invention relates to the technical field of automatic control, in particular to a method and system for intelligently controlling the ventilation system of a grain depot. Background technique

[0002] As an important strategic material of the country, grain reserves have assumed important responsibilities in maintaining the grain market and social stability, protecting the interests of farmers, and ensuring national security. In recent years, with the increase of the country's investment in the construction of grain depots, the grain storage environment of the grain depots has been significantly improved, coupled with the application of some new technologies, the rodents and pests in the grain depots have been effectively controlled, but preventing grain The mildew problem has not been well resolved. After long-term exploration and practice, it has been proved that as long as the temperature and humidity in the granary are effectively controlled, ...
